' Application ined May ze, '1924. serial No. 715,792. i

-Be it known that I, ANTONI SwAnoGZKI, citizen of the United States, residing at Detroit, in thecountyof VVayneand State of Michigan, have invented certainnew and useful Improvementsy in Turbines, of lwhich. the following is aspecification. Y

This invention relatesl to water, gas or steam turbines, the invention having for an object'the provision of a novel type of turbine provided with means for varying the effective area of the blade or vanes, thereof.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the va# rions novel features of the invention are more particularly set forth.

Fig. 1 of the drawing is a face view, with parts'broken away, of'my improved turbine; showing it coupled up with an air compressor or the like to drive the latter.

Fig. 2 is a plan view.

Fig.' 3 is a transverse vertical sectional view thereof, taken approximately along the line 3-3'of Fig. 1.

Referring now to the drawing, my improved turbine comprises a short cylindrical casing which is mounted on an integral base l1, and which is here shown as provided -at opposite ends with the radial flanges 10 to which the face plates 12 are secured as by the bolts 13. These face plates are formed with bearing hubs 111 which support a shaft on which the rotor-of the turbine is mounted. This rotor comprises a member split, transversely of they axis thereof, into two halves 18. Y

This rotor is formed with a series of pockets 20 spaced evenly around the periphery thereof and whose forward walls 21 may be said to constitute vanes or blades against which the motive Huid impinges to drive the rotor. Intake and outlet connections 22 and 23 respectively are provided onthe casing 10. Y

To adjust or vary the effective area of the members 21 I may provide a series of adjustable plates or leaves 25 which are hinged at their forward sides to the rotor, being here shown as hinged On pins 26 fixed at opposite ends in the side walls of the pockets 20, the hinge axes of these leaves being parallel to the rotor axis. The free ends of these leaves are in close contactwith the the inner faces of these leaves.

. pinges.

front wall members 21 which latter are icurved concentric to the hinge axes of the leaves.

The'leaves areadapted to be adjustedoutkward, to vary the effective areal of the mem` bers 21 byV means of cams 28 formed on the periphery of a disk 29 and bearing against This disk 29 is located between the two members 18 of the rotor to be capable of rotary adjustment with respect to the latter, the two members being spaced apart suflciently to` accommodate the disk between them, and may bel secured together byV bolts such as 31 passing through meeting bosses 32 on the respective members which project through arcuate openings 33 in the disk.v o

The disk 29 has connected thereto an elongated hub or sleeve 85 which freely encircles the shaft 15 and which projects through one of the face plates 12 and is locked to the shaft by a set screw 36 or any Othersuitable'means. By loosening this screw, and giving the sleeve a slight rotary movement on the shaft,

the cams 28 may be made to move the leaves 25 outward to diminish the depth of the pockets and thereby lessen the area of the members on which the motive fluid im The sleeve 35 is shown as provided with a projecting pin 38 to be engaged by a suitable spanner when the sleeve is to be adjusted. Springs such as 40 may bear on the leaves 25 to urge the latter inward when adjustmentis made to increase the effective area of the members 21. Y c

I have here shown my improved turbine arranged by means of a novel duplicate drive connection to drive an aircompressor, pumps or the like. crank wheels 445 are mounted on opposite ends of the shaft 15, and are connected by means of the connecting rodsA 46 with the opposite ends of a crosshead bar 17 slidable in fixed guide elements 48 and havingvcon nected thereto midway betweeny its ends the end of the piston rod 49 of the cylinder 50 of the device being driven.

While I have illustrated and described a preferred embodiment of my invention it is to be understood that I do not limit myself to the precise construction herein shown,

andthat various changes and modifications Having-*thus described my invention what As here shown a pair of 1 I claim as new and'desire'to'proteot by Letters Patent of the United States is as follows l. A turbine coinprisinga easing, a-rotor therein, a shaft on which said rotor is fixed, a series of pockets forined in the periphery of said rotor, leaves hinged in said pockets for varying the effective depth thereof, a disk mounted on said shaft for rotary adjustment, and cani elements on said disk for thearing ou theiinner fa'ces-of'said leaves and adapted to adjust the latter outwardto 4deere'asethe depth of said pockets.

"2. A 'turbine comprising a casing, arotor therein, a shaft on which sai'd'rotor is'iXed,

a series of pockets formed in the periphery of said rotor, leaves hinged in said -poekets for varying the effective depth thereof, a disk vmounted on said shaft for rotary adjustment, and cani elements on said disk for bearing on the inner faces of said leaves and adapted to adjust the latter outward to decrease the depth of said pockets, said disk having a sleeve extension surrounding said shaft and projecting from the easing and adapted'to be fixed to the shaft to secure the disk in adjusted position thereon.

:In testimony whereof I-have affixed niy .ANTONI 'SIVAROCZKI signature.
